What causes a runaway diesel motor?

Diesel engine runaway occurs when a diesel engine ingests a hydrocarbon vapor, or flammable vapor, through the air intake system and uses it as an external fuel source. As the engine begins to run off these vapors, the governor will release less diesel fuel until, eventually, the vapors become its only fuel source.

Why do diesels rev so low?

What fluids will destroy a diesel engine?

Thousands of diesel engines fail prematurely each year aided by the presences of glycol, fuel, soot and water in the engine oil.

Is it bad to redline a diesel?

No, engines have RPM limiters to avoid damage. Being a diesel, it would burn more fuel at higher rpms but produce less torque, and it would come with literally no benefits. It won’t hurt the engine though. Higher rpm equals higher load equals higher wear.

Can a non turbo diesel runaway?

There’s been a lot of buzz lately on social networks around videos of diesel trucks that are bellowing white smoke and suddenly die. No, the truck isn’t doing a huge burnout. It can happen to any diesel engine in any vehicle, but more commonly in turbo-diesel applications. …
